Rokinon 14mm F 2 8 EF Avis | 54 Données comparées

The Rokinon 14mm f/2.8 ED AS IF UMC is a highly affordable, ultra-wide-angle manual lens that delivers outstanding optical performance, especially on full-frame cameras. Its greatest strength lies in its exceptional sharpness, which dramatically outclasses more expensive competitor lenses by resolving fine detail even into the far corners of the frame. Additionally, it features excellent color rendition, strong microcontrast, and remarkable resistance to flare when shooting directly into the sun. For astrophotographers and nightscape enthusiasts, it serves as an industry favourite due to its highly controlled chromatic aberration and incredibly low coma, keeping stars perfectly crisp without distorting them into irregular shapes. However, the lens comes with several design and usability trade-offs. Because it lacks electronic coupling, users must tolerate completely manual focus and manual aperture control, which also leaves images without focal or aperture EXIF data. Optically, its biggest flaw is a heavy, complex "mustache-style" barrel distortion exceeding 5%, making it poorly suited for architectural or real estate photography without tedious post-processing corrections. The physical design presents additional liabilities; its bulbous front element and permanent petal-shaped hood prevent the...

The Samyang/Rokinon 14mm f/2.8 IF ED UMC is a highly affordable, fully manual ultra-wide-angle lens designed for full-frame and sub-frame DSLR cameras. Retailing at a bargain price of around $330, it serves as a budget-friendly alternative to premium competitor offerings from Canon, Nikon, and Zeiss, which can cost five to nine times more. Built with a solid metal barrel and mount, the lens features a silky smooth manual focus ring with a generous 250-degree throw that allows for precise fine-focusing adjustments. However, users must adapt to its fully manual nature, which completely lacks autofocus, image stabilization, or electronic communication with the camera body, requiring manual exposure adjustments via a thin plastic aperture ring. Optically, the lens is a mixed bag that prioritises sharpness and excellent chromatic aberration control over other distortions. Its main advantages include extremely sharp image quality across the frame—even when shot wide open—and effectively minimised colour fringing on both full-frame and sub-frame sensor bodies. Conversely, its primary drawbacks are severe vignetting and heavy barrel distortion; on a full-frame camera, light loss reaches nearly two stops at f/2.8,...

The Samyang/Rokinon 14mm f/2.8 ED AS IF UMC is a budget-friendly, ultra-wide rectilinear lens designed for full-frame cameras, costing a fraction of its Canon equivalent. On the positive side, the lens delivers excellent sharpness and contrast when stopped down to f/8, boasting almost non-existent chromatic aberration that even outperforms much more expensive lenses. It features a smooth, manual focus ring with a long focus throw, and despite its lightweight plastic build, the construction feels robust and solid. Furthermore, its wide depth of field at smaller apertures makes it easy to capture sharp landscapes and street photography without relying heavily on precise focusing scales. However, the lens comes with notable downsides, primarily its fully manual nature and complex distortion. There is no electronic communication with Canon cameras, meaning autofocus, focus confirmation, and automated EXIF data logging are completely unavailable. Additionally, the lens exhibits strong, wavy "moustache" geometric distortion that makes straight lines warp significantly. While this rendering quirk is less noticeable in nature shots, it makes the lens problematic for architectural photography unless heavily corrected using dedicated software profiles. Vignetting is...

The The-Digital-Picture review highlights the Rokinon AF 14mm f/2.8 lens as a high-value, ultra-wide-angle option delivering excellent sharpness, effective autofocus, and a robust, weather-sealed construction. Ideal for landscape and astrophotography, this compact lens offers a 116.6° field of view, providing impressive optical performance at a competitive price point. The-Digital-Picture.com Key limitations noted include the inability to use standard threaded front filters due to the bulbous lens element and fixed hood, alongside significant barrel distortion. Additionally, as a third-party lens, it may exhibit minor, infrequent autofocus inconsistencies with certain older DSLR camera bodies.

The Samyang 14mm f/2.8 IF ED UMC lens offers exceptional value, delivering high center sharpness at f/2.8 and a very wide 115.7-degree angle of view suited for landscape and astrophotography. It is characterized by solid construction and a smooth manual focus ring, providing excellent performance for its price point. YouTube · However, the lens has significant drawbacks, including severe, complex "moustache" barrel distortion and heavy vignetting, requiring extensive post-processing. Furthermore, it is a fully manual lens lacking autofocus and chip communication, while the bulbous front element prevents the use of standard filters.

The Rokinon 14mm f/2.8 IF ED UMC is a high-value, fully manual ultra-wide lens renowned for its professional-grade sharpness at a budget-friendly price point of approximately $320 USD. Its primary strengths include exceptional edge-to-edge clarity and industry-leading performance in minimizing coma aberration, making it a "must-have" for astrophotography and expansive landscape shots. The build quality is surprisingly robust for the cost, featuring a long-travel focus ring that allows for precise manual adjustments, even when shooting wide open at f/2.8. Despite its optical prowess, the lens presents several functional trade-offs, most notably the total lack of autofocus and a manual aperture ring, which may alienate photographers accustomed to automated systems. Specific technical drawbacks include noticeable "moustache" distortion and a high susceptibility to lens flare. Additionally, users have reported inaccurate distance scales on the lens barrel and inconsistent quality control, which can lead to uneven sharpness across the frame in some units.

The Rokinon 14mm F/2.8 lens is a highly capable and budget-friendly ultra-wide-angle manual prime lens designed for astrophotography, offering a 115.7-degree field of view on full-frame cameras and a 94-degree field of view on crop-sensor bodies. A major advantage of this lens is its low price point of $299 USD, making it significantly cheaper than comparable models from Canon or Nikon while still providing fast optics and a solid build quality. It excels at capturing expansive panoramic-style images of the Milky Way, constellations, and low-light video footage, especially when paired with a small tracking camera mount. However, users must adapt to several drawbacks, as the lens is fully manual with no autofocus capabilities or electronic camera communication, requiring manual adjustments via a physical aperture ring at the base that displays "0" on the camera's screen. Optically, while star sharpness is exceptional when stopped down to a recommended versatility setting of F/3.2, shooting wide open at F/2.8 requires incredibly precise focus and introduces optical flaws. These optical cons include distinct signs of color fringing (chromatic aberration) and elongated stars (coma) near...
